T0 at whom it may concern:

Be it known that 1, JAMES HA EY GREEN- WOOD, a subject of Her Majesty the Queen of Great Britain, residing at Boissevain, county of Turtle Mountain, Province of Manitoba, Canada, have invented certain new and useful Improvements in Mechanical Brakes; and I do hereby declare that the following is a full, clear, and exact description of the invention,

such as will enable others skilled in the art to letters of reference indicate similar parts, Fig-- ure 1 is a plan view of the frame of a car provided with a brake mechanism constructed in accordance with 'this invention. Fig. 2 is a transverse section taken on the line 2 2 of Fig. 1. Fig. 3 is a central longitudinal section showing the position of the parts when the brake is off. Fig. 4 is a similar View showing the position of the parts when the brake 1s on.

In the drawings, A represents the frame of a car, which may be of any usual or preferred construction, having the usual trucks, 85c. Upon the beam ct is rotatably mounted the bar a, to the ends of which are secured suitable wires or rods a and a whereby the bar a is connected with the lever B and to the brake-beams (L as best shown in Figs. 3 and 4. The leverBis fixed upon a shaft 17, which is journaled in suitable hearings in the lower end of a bracket b, fixed upon the frame of the car. The upper end of the lever Bis connected by suitable rods b with the ends of a draw-bar B, which is slidably secured to the coupler B by means of a pin-and-slot con nection. As the coupler is pivotally supported upon the frame of the car, so as to permit of its lateral movement, the draw-bar B will also have a corresponding lateral movement ,whereby it is adapted to be coupled and uncoupled with the next car by the movement of the coupler-bar.

It is apparent, in view of the above description, that, the draw-bars B being connected throughout the train to the engine, the engineer is able to operate the brakes throughout the train by moving the draw-bars longitudinally through the medium of a lever or other suitable device. (Not shown.)

The operation of the improved brake mechanism will be sufiiciently obvious in view of the above description without furtherdetailed explanation.

While I have herein shown a preferred form of carrying my invention into eifect, yet I do not desire to limit myself to such preferred details of construction, but claim the right to use any and all modifications thereof which will serve to carry into effect the objects to be attained by this invention,in so far as such modifications and changes may fallwithin the spirit and scope of my said invention.

I claim The combination with a brake mechanism, and draw-bars slidably mounted on a car for connection with and disconnection from other
